First, I assume you meant "C-h i", not "C-h C-i".

Second, what does ``can't display the info page'' mean, exactly?  What
happens after "C-h i"?

There are several ways.  If you are sure you are looking for the C
library function `printf', type "C-h S c-mode RET printf RET".

If you are not sure what `printf' you are looking for, try "M-x
info-apropos RET".

(The above might not work if you are not running Emacs 22.)

Inside Emacs, use Info first, and if you cannot find the documentation
of whatever you are looking for, I suggest to use woman, since it's
more portable across platforms supported by Emacs.
